对中国与瑞典的２０００余辆卡车、公共汽车腐蚀状况的调查揭示了对腐蚀最敏感的部件及改变材料和施以表面保护对腐蚀的影响。同时在中国６个、瑞典３个试验点进行腐蚀性及环境因素影响的挂片试验，对汽车底部的挂片包括采用不同的结构材料、涂漆及临时防锈剂，研究开放表面及缝隙内的腐蚀行为。对汽车板腐蚀机理及影响因素、室内外加速腐蚀试验方法进行了初步探索。
In a co-operative Chinese-Swedish research project an investigation on the cor- rosion status of 2000 trucks and buses in China and Sweden has revealed the parts most sen- sitive to corrosion attack and the influence of changes in material or of the surface protective means on corrosion behaviors. In a stationary exposure at 6 Chinese and 3 Swedish sites the corrosivity of coupous and the effects of environmental parameters have been investigated. An extensive coupon exposure under buses displayed corrosion behaviors on free surfaces and in crevices, involving different construction materials, painting systems and temporary an- tirust agents. The corrosion mechanism of materials used for automobile, the affecting fac- tors, accelerated outdoor and indor corrosion test methods have also been researched.
